Abstract [en]

In this study, a fast, low cost and reliable methodology for bipolar plate material screening and testing is presented. Ex-situ measurements of contact resistance are used as a screening tool, while in-situ measurements such as: fuel cell performance, in-situ contact resistance, high frequency impedance spectroscopy, together with post analysis of stainless steel surfaces, MEAs and fuel cell effluent water evaluates the real performance of the most promising stainless steels and coatings, providing reliable data for future fuel cell stack test.
